To afZZ whom t may concern:l

Be it known that l, H ENRY E. BUTTS, a citi- -zen of the United States,residing at Detroit,

in the county of Vayne, State of Michigan, have invented. certain newand useful Improvements in Car-Nheelsg and I d declare the following tobe a full, clear, and exact description of the invention,sucb. as willenable others skilled in the art to which it appertains to make and usethe saine, reference being had to the accompanying drawings, and to theletters of reference marked thereon, whichform a part of thisspecification.

`This invention relates to new and useful improvements in car-Wheels,and consists in the construction and arrangement of parts, ashereinafter 'fully set forth, the essential features of which beingpointed out particularly in the claims.

The object of the invention is to provide a A car-wheel with a pneumaticor iniiated cushion interposed between the hub and tread of the wheel,whereby the concussion caused by contact of the tread of the wheel withthe rail, is absorbed by said' cushion, and is not imparted to the carthrough the axle; making a Wheel that travels along the railwith butlittle noise, and by means of which the shock and jar, incident `toordinary railway travel, may be greatly overcome, alsoobviating-orystallization and breakage of the axle, and reducingthe wearen the rail and wheel-tread. These objects are attained by thcconstruction illusthereto by the transverse bolts la, as clearly.

shown in Fig. 2.

disks A concentric with ythe hub audfinl the y space around said hub,between its periphery sesamo. 432,57. cromati.)

and said ring is run cement or other suitable filling D.

Lying in the hollow of the ring C, and embraced by the disks A, is aring o't' rubber or analogous materialE, which is provided with acircular air space c, and a series ot verse apertures e, through whichfreeiy pass the .bolts f, which couple the outer edges of train-ineledaction of the rubber is permitted, and its native resiliency preserved.

The ring C isprovidcd with a tube d, that communicates with .an openinginto the airspace in the rubber ring, controlled by a spring actuatedvalve h, and with an aperture through which air may be forced into vthespace o, until any desired pressure is attained.

by a screw-plug z', whereby double provision is made against leakage,and dust is excluded. from the valve h.

F indicates a rolled-steel riin, to which the vtread G, having theflange t', is cast. ,This rim is also embraced bythe disks A, and bearsupon the periphery o therubber E, the inner edge of said disks beingprovided with the beads or anges n, that lie in the circular ways o inthe sides of said rim, which freely receive said flanges so as to permitof the di-4 ametrical reciproeaticn of said rim between said disks. Bywhich construction the hub is suspended, by means of an air cushion,within the rim of the Wheel. Nhereby the vibration of the wheeltraveling along the rail, is abis greatly reduced.

instead of employing the rolled-steel rim F, and casting the treadtheretc, said rirn'and vtread. may be formed integral if desired. Theanges n of the disks'A engaging in the ways in the sides ot' the rim,prevent a segment ot' the 'rirrkfrom dropping out, should said rimbecom'e'broken.

Having thus'fully set forthv my' invention, what` I claim as new: anddesire to secure by Letters Patent,'is C is a concaved ring locatedbetween the I l. in anar-wheel, the combination of the epposed disks,the hub mounted therein, the diametrical-ly ad :instable traademhracedby said the disks A. By which arrangementthe un through one of the sidedisks A of .the wheel,

Said aperture through the disk being stopped soi-bed, and the soundcaused by such 'travel EGG disks, the resilient cushion interposedbetween said disks and lying against said tread, said cushion having aseries of apertures passing transversely therethrough, the series ofstay bolts coupling said disks and passing freely through said aperturesin said cushion.

2. In a car-wheel, the combination 0f the hub, the web composedof theopposed disks, the tread embraced by said disks and having thediametrical lugs s, the resilient cushion interposed between the hubandtread and having recesses' in its rim that receive the lugs of thelatter.

3. In a carwheel, the combination of the hub, the opposed disks forminga hollow web the diametrically adjustable tread, embraced by said disksthe inflated cushion interposed between said disks and bearing on thetread,

the non-metallic filling between said cushion' and hub and tread.

Je. In a car-wheel, the combination of the opposed disks, the hubmounted therein, the diametrically adjustable tread embraced by saiddisks, the pneumatic cushion interposedbetween said hub and tread,substantially as specified.

In a car-wheel, the combination of the opposed disks, the hub mountedtherein, the dibearing against the tread, the filling `between` said huband cushion. .y i

8. In a car-wheel,the combination oi the hollow vlieb, thehub, thetread, the hollow flexible cushion, interposed between said, tread andhub, and bearing against the former the duct' passing through the weband communicating with the space in said cushion, substantially V i asspecified.

In testimony whereof I aliig inysignature i n presence of two witnesses.
